PHOTOGRAPHIC CAMERA.

SPECIFICATION forming part of Letters Patent No. 759,114, dated May 3, 1904. Application filed September 12, 1902. Renewed March 31, 1904:. Serial No. 200,953. (N0 model.)

To all whom it may concern.-

Be it known that I, EMIL KRONKE, a subject of the King of Saxony, residing at 1 Linden Platz, Dresden, in the Kingdom of Saxony, Germany, have invented new and useful Improvements in Photographic Cameras, of which the following is a specification.

Photographic cameras inclosed within the handle of a walking-stick, and thereby rendered particularly suitable for use in traveling, were described in the British Patent No. 13,686 of 1891 and the German Patent No. 94, 7 48. Inasmuch, however, as those cameras are capable of' receiving but a small number of picture-surfaces z'. 6., plates or films they necessarily permit only a correspondingly small number of photographic views to be taken unless an extra supply of spare films or plates be keptin reservesay in ones coatpocket or carried in a satchel or bag or otherwiseso that the surfaces in the stick may be replaced by new ones when used up. Apart from other drawbacks, however, this exchange is a complicated operation, which in certain places and circumstances it may be difficult or impracticable to carry out, more especially where the surfaces to be dealt with are of the class which cannot be exposed to daylight, as are those, for example, referred to in connec tion with the camera forming the subject of the said German Patent No. 94,748.

Now this inventionrelates to a camera constructed in the shape of a walking-stick handle, which differs from the two above-mentioned arrangements in this particular, that within the walking-stick handle room is provided not only for the camera itself and the roll of film intended for immediate operation, but in addition to this for a number of extra rolls,which are so arranged that their substitution for those exhausted by exposure can in each case be readily efiected.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of the combined walking-stick handle and photographic camera, showing its inner arrangement, while Figs. 2, 3, and 4: are sections of Fig. 1 along the lines A B, C D, and E F, respectively; and Fig. 5 is a detail view of an indicator for determining the extent to which the, receiving-roll is to be turned after each exposure of the film.

The crook-shaped handle is made of thin material, and consists of two parts a and b, the plane of division between which is vertical and parallel to the longitudinal axis of the handle; one part, a, which after the known manner of the lids of boxes, fits over a pro jecting rim of the other part, b, and is removable. The interior cavity of the handle is divided by a vertical plate 0 into two compartments d and e, the compartment (Z forming the camera. Thelensf of the camera is inserted into the front of the handle, which is provided with a light-aperture. The shutter g, by which this aperture is controlled, is placed within the camera-compartment in the rear of the lens. The shutter may be constructed for either time or snap-shot exposures. As shown in Fig. 2 by way of example only, it may comprise a shutter consisting of two parts mounted on a hinge-pin common to both and adapted when an exposure is desired to swing under the action of a pin it, being drawn out axially by the operator.

The sensitized picture-surface intended to be used in this camera is by preference a film-roll arranged for being changed in daylight. The roller carrying the unexposed film c' is arranged behind the plate 0, which plate at the same time serves the purpose of guiding thefilm and keeping it in the focal plane for exposure.

The roller or spool whereon the film-band winds after exposure is placed in the hollow space it of the neck of the handle, which space for this purpose is made inaccessible to light from above by means of a screen Z. The spindle 02 carries the receiving-spool m and is adapted to turn in the winding direction. A ratchet-wheel 0, also mounted thereon, and a catch or pawl p, engaging therewith, prevent rotation in the wrong direction. The distance or extent to which the said spindle a is to be turned to cause the exact length of film that has in each case been exposed to be wound on the spool m is marked by an index q, mounted on the button or knob r, whereby the said spindle is turned, as illustrated in Fig. 3, a scale, as shown in Fig. 5, for the said index to move over being placed around the said knob r on the outer wall of the said space or casing Z'. (See Fig. 5.)

The compartment 0 of the crook-handle of the stick in addition to accommodating the roll of unexposed film which is being used from is at the same time utilized for storing an extra supply of film-rolls. The spools which carry the film s are preferably made of thin metal. The bearers of these spools are hollow spindles or pins 3, secured in the wall of the compartment 0 and slotted longitudinally, so that the spools may readily be passed over them, after which, owing to the resilience of the hollow bearers, the spools are securely held in place thereon, such resilience or spring action at the same time operating as a check or brake upon the film as it is delivered to the camera for exposure.

As the film-rolls which it is proposed to employ in this camera are prepared for changing in daylight, the exchange of a roll of film that has been exposed for a new one may be effected with the utmost rapidity when or Wherever required. It is only necessary to remove the portion a, which forms the lid or cover, when all the spools in the handle will become accessible, so that the film-renewing operation simply consists in removing the spool carrying the roll of film already exposed, transferring the spool which is empty and one of the spools of unused film, respectively, from one spindle to another, and then attaching the end of the new film to the empty spool for receiving the film after exposure and shutting the lid, when all is once more ready for immediate use.

Assuming that the spools or rollers of the size indicated in the drawings are employed, these being calculated for twenty exposures each, and that five such film-rolls are inserted in the stick, as shown, it will be seen that one filling or charge of the portable camera will be suificient for one hundred photographic pictures.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In a cane, having a hollow top, the combination of a photographic-camera attachment thereon, a compartment for supporting a plurality of film-rolls and a detachable side for the top of the cane.

5. The combination of a cane, having a hollow handle, of a camera attachn'ient for the handle having three chambers, separated by screen-plates, one of said chambers being fitted with lensf' and shutters g, operated by a pin it, another of said chambers being fitted With a Winding-spindle m, and ratchet-wheel 0 and pawl 19, and the other chamber being fitted with pins for holding reserve rolls of films, all of said chambers being inclosed by a detachable side for the cane-handle.
